The Research And Application Of Power Grid Distribution Intelligent Supervisory Control Order System

Dongguan Power Grid has a maximum load of over 15.5 million kilowatts in 2018,which is already the highest municipal power supply bureau of Guangdong Power Grid.With the rapid growth of the power load and the expansion of the power grid,the maintance and justment of power grid equipment keeps increasing,which has caused great operational pressure on dispatching and monitoring positions.The current text format of the dispatch monitoring operation ticket can hardly meet the normal operation and accident treatment requirements of the power grid.The integrated regulation and control work of China Southern Power Grid,provides an important solution to solve this kind of problems.The combination of scheduling and monitoring is called the controller,and the controller directly operates the jurisdictional equipment,which is an inevitable trend of the development of the grid dispatch.At present,the electronic order of telephone or web text format widely adopted by Dongguan Power Grid has room for improvement in efficiency and security.This paper,mainly introduces the whole process of Dongguan intelligent supervisory control order system,and carries out the detailed research of the construction of technical requirements of monitoring operation.Based on the actual operation,we designed the five-prevention rules,state check rules,power flow check rules,order check rules,and operation check rules for the dispatching operation tickets.Among them,the rules of order check areformulated according to the regulation of dispatching to prevent personal operation safety,which has good practical application value.At the same time,by using the intelligent dispatch monitoring and control ticket system,Dongguan Power Supply Bureau achieved the first programing dispatching operation of 500 kV line in China,which effectively demonstrated the efficiency and security of the intelligent dispatch monitoring and operation ticket system.In addition,this pilot also combines various intelligent means such as robot position inspection to effectively improve the intelligent level of the power grid.
